Patent CA-2046245-A1 (CA)
Title: Scroll type compressor with variable displacement mechanism
Inventor: MATSUDAIRA YASUYUKI
IPC: F04C27/00
Filed: 1991-07-04
Abstract: A scroll type compressor with a variable displacement mechanism is disclosed which includes a housing with an inner chamber and fluid inlet and outlet ports connected to the inner chamber. A fixed scroll, which is mounted within the housing, has an end plate from which a first spiral wrap extends. An orbiting scroll also is mounted within the housing for orbital motion with respect to the fixed scroll. The orbiting scroll has an end plate from which a second spiral wrap extends. The first and second wraps interfit to define at least one pair of sealed off fluid pockets. The end plate of the fixed scroll partitions the inner chamber of the housing into a suction chamber and rear chamber. The rear chamber includes an intermediate pressure chamber which communicates with the sealed off fluid pockets through a pair of circular holes formed at the end plate of the fixed scroll. A control mechanism controls fluid communication between the intermediate pressure chamber and the suction chamber. A plurality of seal elements are sequentially located along the axial end of the second wrap such that the spaces between the seal elements cross over the circular holes during orbital motion of the orbiting scroll. Thereby, the diameter of the circular holes may be enlarged to prevent constriction of the flow of fluid through the holes during high rotational operation of the compressor, without increasing the possibility of damaging the seal elements due to the seal elements being sandwiched between the spiral wrap and the holes.

Title: Photoplethysmographics using energy-reducing waveform shaping
Inventor: MCCARTHY REX
IPC: A61B5/00
Filed: 1992-03-04
Abstract: Photoplethysmographics Using Energy-Reducing Waveform Shaping Abstract A method of energy-reducing waveform shaping of carrier signals in a photolethysmographic system, in which a carrier signal may comprise a time-varying peri-odic waveform comprising a sum of carrier components. The carrier signal has its energy reduced by adding additional carrier components, which reduce the energy envelope for a period of the carrier signal, while preserving the sig-nal information. The method of energy-reducing waveform shaping may be coupled with frequency-division multiplexing, and more generally with any method of multiplexing which employs a time-varying periodic carrier signal. Redundant information may be used for error detection and correc-tion. A plurality of carrier components may be chosen which reduces the energy envelope for a period of the car-rier signal, and which employs more carrier components than needed to perform the preferred form of multiplexing and demultiplexing of the modulation effects introduced by a tissue section of the patient. Majority voting of car-rier components may then provide for error detection and correction.

Title: Systems for encoding and decoding data in machine readable graphic form
Inventor: WANG YNJIUN P
IPC: G06V30/224
Filed: 1992-03-16
Abstract: ABSTRACT      A system for representing and recognizing data in machine readable graphic image form in which data to be encoded is entered into the system and a processor encodes the data into a two-dimensional bar code symbol and generates transfer drive signals representative of the symbol.  A transferring device such as a printer transfers an image of the two-dimensional bar code symbol onto a carrier such as a card or paper document in response to the transfer drive signals.  A recognition device converts the image on the carrier into electrical signals representative of the symbol by scanning the image.  A low-level decoder decodes the signals by decoding each scan line into a vector of codeword values corresponding to the codewords in the two-dimensional bar code symbol, assigning a row number to each of the codeword values, and then filling in a two-dimensional matrix with the codeword values.  A high-level decoder further decodes the codeword values into data which can then be output for processing or use.

Patent CA-2075518-A1 (CA)
Inventor: INUI TETSUYA
IPC: G11B7/2405
Filed: 1992-08-07
Abstract: A transparent substrate of an optical memory is produced by injection molding using a stamper. Grooves and lands are alternately arranged on the optical memory, to facilitate the tracking of light converged on the optical memory. The groove width is set in the range of 0.3 µm to 0.4 µm and the groove depth is set in the range of 80 nm to 100 nm. A decrease in the width of a land is restrained to a maximum of 0.2 µm at each edge. With such dimensions, even when the track pitch is set to about 1.4 µm, it is possible to obtain a track crossing signal with sufficient intensity for performing an access operation to a target track. Moreover, since the dimensions bring about an improved reflectance at a land, the optical memory achieves an improved C/N ratio and recording density.

Inventor: GUENA JEAN
IPC: G01S13/84
Filed: 1992-09-15
Abstract: An emitted wave is transmitted from a central station to a passive end. A phase modulation circuit in the passive  end modulates  a  signal resulting  from the emitted wave for retransmitting it in the form of a two-phase-state modulated signal at the rhythm of a clock signal.  In the central station,  the modulated signal is demodulated into two quadrature signals. On the basis of the product of the two quadrature signals and the sign of the difference between the moduli of the rectified quadrature signals, the count of an up-down counter  in  a  digital  processing  circuit  is incremented or decremented in order for said count to be  representative  of  the  distance  separating  the passive end and the central station.

Title: Arrangement in a two mast platform
Inventor: JOHANSSON AKE
IPC: B66F11/04
Filed: 1991-08-28
Abstract: The invention relates to an arrangement in an elongated working platform (2) which at each end is carried by a mast via a drive support (8) movable along the mast. The drive support includes an electric motor unit by means of which the drive support is drivable along the mast, said drive support pivotally carrying the corresponding end of the platform.
